Description
Featuring the unique Eighteen Sound elliptical shape (ESS technology), the XT1086 Constant
Coverage High Frequency Horn has been designed for use in sound systems where the highest
sound quality is required. With a 1 inch throat entry, the XT1086 has been designed to match the
Eighteen Sound 1 inch exit high frequency compression drivers perfectly. The XT1086 maintains
nominal 80° Horizontal x 60° Vertical pattern control. It provides consistent on-axis and off-axis
frequency response from 1,4kHz to 16kHz in the horizontal plane and from 1,5kHz to 16kHz in
the vertical plane. Horn directivity is constant from 1,4kHz. Thanks to its compact vertical mouth
dimension, the XT1086 can easily be staked vertically when lower frequency control is required.
The main innovation that the XT1086 introduces, is the improved external shape, providing high
structural rigidity. This has been developed using exclusive a computer aided vibration analysis
system. This product provides low distortion and a spherical wave-front, avoiding reflections
and other disadvantages usually associated with diffraction horns. The die-cast aluminum
construction provides optimum heat transfer, lowering the driver power compression and
improving its general power handling capability.
